Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment composition for imparting hair / strain to hair.

[0002]

2. Description of the Related Art Among the worries about hair, there are not a few problems related to low elasticity of hair, such as lack of elasticity / strain and lack of volume. In order to satisfy the desires of those who have these concerns, many hair treatment agents have been used in the past, which contain a balm / strain-imparting agent and a conditioning agent. However, most of these are effective due to adsorption of the agent on the hair surface, etc., and are dropped during hair washing. Therefore, the treatment must always be performed, which is troublesome. In addition, trials have been made to penetrate the inside of the hair to exert the effect, and for example, it has been reported to treat the hair with an aqueous solution of naphthalenesulfonic acid (J. Soc. Cosmet. Chem., 36 ,. 87
~ 99, 1985). However, this also has poor penetrability into hair, requires a long treatment time, and is not sufficiently effective.

[0003]

Under such circumstances, the present inventor has conducted diligent research and as a result, a treatment agent prepared by combining azulene sulfonic acids and an organic solvent was found to improve the elasticity of hair in a short time. The present invention has been completed with the finding that it improved, gave the hair a firmness / strain, and that this elasticity was retained for a long time.

Therefore, the present invention provides a hair treatment agent containing an organic solvent and azulene sulfonic acids.

In the present invention, examples of azulene sulfonic acids include guaiazulene sulfonic acid, 1-azulene sulfonic acid, 3-acetyl-7-isopropyl-1-
Azulene sulfonic acid, 3- (2-hydroxyethyl)-
7-isopropyl-1-azulenesulfonic acid, 3-methyl-7-isopropyl-1-azulenesulfonic acid, 7-
Isopropyl-1-azulenesulfonic acid, 3-phenyl-6-isopropyl-1-azulenesulfonic acid, 1,4
-Dimethyl-7-isopropyl-2-azulenesulfonic acid, 4-ethoxy-3-ethyl-6-isopropyl-1
-Azulene sulfonic acid, 1,3-azulenedisulfonic acid, 4,6,8-trimethyl-1,3-azulenedisulfonic acid, 1,3-bis (1,1-dimethylethyl)-
5,7-azulenedisulfonic acid, 1,3-bis (1,1
-Dimethylethyl) -5-azulenesulfonic acid, 3-formyl-4,6,8-trimethyl-1-azulenesulfonic acid or salts thereof. Examples of such salts include sodium salts, potassium salts, calcium salts, ammonium salts, and organic quaternary ammonium salts.

The amount of azulene sulfonic acid compounded is 0.1
10% by weight (hereinafter, simply indicated by%), particularly 1 to 5% is preferable. If it is less than 0.1%, the effect of hair treatment is not sufficient, and if it exceeds 10%, the effect corresponding to the increase cannot be obtained.

In the present invention, the organic solvent is a compound represented by the following formula (1) or N represented by the following formula (2).
-Alkylpyrrolidone or alkylene carbonates having 1 to 4 carbon atoms.

Specific examples of these organic solvents include ethanol, isopropanol, n-propanol,
n-butanol, isobutanol, ethylene glycol, propylene glycol, 1,3-butanediol,
Benzyl alcohol, cinnamyl alcohol, phenethyl alcohol, p-anisyl alcohol, p-methylbenzyl alcohol, phenoxyethanol, 2-benzyloxyethanol, methylcarbitol, ethylcarbitol, propylcarbitol, butylcarbitol,
Triethylene glycol monoethyl ether, triethylene glycol monobutyl ether, glycerin, N-
Methylpyrrolidone, N-octylpyrrolidone, N-laurylpyrrolidone and the like can be mentioned.

The blending amount of such organic solvent is 0.5 to 50.
%, Especially 2 to 30% is preferable. If it is less than 0.5%, the effect is not sufficiently exerted, and if it exceeds 50%, the effect is not improved. The mixing ratio of water and the organic solvent depends on the water solubility of the solvent, but solvent: water = 20: 80-
50:50 is preferable.

To the hair treatment composition of the present invention, an acid or an alkali is further added to adjust the pH of the hair treatment agent to a specific range so that the hair is sufficiently swollen and the naphthalene sulfonic acids are allowed to penetrate into the hair. Effective to promote. That is, it is preferable to adjust the pH of the composition to 2 to 5 when adding the acid, and to adjust the pH of the composition to 8 to 11 when adding the alkali. If the pH of the composition is below 2 or above 11, the hair may be damaged. Regarding the swelling of hair by acid or alkali, the research report by Bat et al. [G. Ramachandra Bhat e
t. al. , J. Soc. Cosmet. Chem. ，
32f, 393-405 (1981)], and hydrochloric acid is used as an acid and sodium hydroxide is used as an alkali in this research report. However, since the hair itself is an ion exchanger, the acid is used as an acid in the present invention. Is preferably an organic acid or phosphoric acid, and the alkali is preferably ammonia or an organic amine.

The above-mentioned organic acids include citric acid, glycolic acid, succinic acid, tartaric acid, lactic acid, acetic acid, fumaric acid, malic acid, levulinic acid, butyric acid, valeric acid, oxalic acid, maleic acid, phthalic acid, mandelic acid. Etc. Examples of the organic amine include monoethanolamine, diethanolamine, triethanolamine, aminohydroxymethylpropanediol, 2-amino-2-methyl-1.
-Propanol, 2-amino-2-methyl-1,3-propanediol, and basic amino acids such as arginine.

These acids or alkalis can be used alone or in combination, and the amount of which the pH of the composition is in the above range is preferably 0.3 to 50% in the composition, more preferably 0.1%. 5 to 30% is blended. If the blending amount is less than this, there is no swelling effect due to the ion-exchange ability of hair, and further blending does not show any further increase in the effect.

In the hair treatment composition of the present invention, the balance of components other than the above-mentioned organic solvent, azulene sulfonic acid and acid or alkali is usually water. In addition, the hair treatment composition of the present invention includes sodium salts, potassium salts of organic acids,
It is preferable to add an ammonium salt or the like to form a buffer system.

Furthermore, in the hair treatment composition of the present invention, a thickening agent such as hydroxyethyl cellulose, a surfactant, a perfume, a pearling agent, a dye, and the like may be added, if necessary, within a range that does not impair the effects of the present invention. You may mix | blend a ultraviolet absorber, an antioxidant, a preservative, etc. Further, in order to improve the feel of hair or skin, a cationic polymer such as cationized cellulose and a silicone derivative such as dimethylpolysiloxane or amino-modified silicone can be blended.

The hair treatment composition of the present invention can be used, for example, by applying it to hair for a certain period of time, preferably 5 to.
After leaving it for 30 minutes, it may be washed out. While standing, it may be heated to a suitable temperature, preferably 30 to 50 ° C. The hair to be applied may be dry or wet after washing.
